Eagle Ford 351W 4.170in Crank 6.250in H-Beam -16cc 4.040in Pistons Balanced Assembly

When you're building a Ford 351W for serious performance, starting with a balanced rotating assembly like this one from Eagle is a smart move. This assembly includes a 4.170-inch forged 4340 steel crankshaft, 6.250-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, and 4.040-inch Mahle forged pistons with an inverted dome design that creates a -16cc volume. It also comes with plasma-moly file-fit piston rings and King XP rod and main bearings, all balanced as a complete unit. This means you get a well-matched set of components that are ready to go, saving you time and ensuring proper balance for your engine build.

This assembly is designed for demanding applications, including racing use with nitrous or forced induction. The forged 4340 steel crank and H-beam rods are strong choices for handling the extra stress these setups can create. The Mahle pistons are forged from 4032 aluminum, known for its durability and good thermal expansion properties, and the -16cc inverted dome helps achieve a desired compression ratio when paired with appropriate cylinder heads. The inclusion of King XP bearings means you're getting robust lubrication and wear protection right out of the box. Remember that these components are file-fit, so you'll need to ensure the piston rings are correctly gapped for your specific application during installation.

This balanced rotating assembly is a solid foundation for a high-performance Ford 351W engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and consult with a qualified engine builder to ensure proper assembly and tuning for your specific build.
